SPINDLE-BEARING FOR SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 460,00*?, dated September 22, 1891.

Application filed April 28, 1891. Serial No. 390,820. (No model.)

To all whom, it may concern.:

Be itknown that CHARLES E. GETCHELL, of Bonds Village, Palmer, Massachusetts, have invented an Improvement in Spindle- Bearings for Spinning and Twisting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Many dilferent plans have been devised for supporting the spindles in spinning-machines in such manner as to enable them to be rotated with the minimum of friction.

Some spindle-supports have been provided with roller or ball bearings; and this invention has for its object to improve that class of bearings having balls or rolls.

In accordance with my invention the rolls are held in place in a peculiar manner and by peculiar devices, which I will describe.

Figure l in vertical section shows a spinning-spindle bearing containing my invention, the spindle represented in elevation having a bobbin thereorin section. Fig. 2 is an enlarged section in the line Figi; and Fig. 3 is a modication of my invention.

Referring to the drawings, A represents a supporting-case having a iange to rest upon any usual post or bolster-rail of a spinning- 3o machine, the shank of the supporting-case below its shoulder being provided with a screw-thread, as a', to in practice receive any usual nut or device employed to secure the supporting-case in position upon the rail. I have placed within the supportingcase a separating-sleeve c, having its ends suitably beveled to act against rolls c c', the bearingsleeve determining the distance apart of the said balls with relation to the length of the spindle. The upper end of the supportingcase has an inturned flange d, against which is placed a collar e, beveled at its lower end next the upper beveled end of the sleeve c, the rolls c being confined in the space between the beveled ends of the collar and sleeve and the periphery of the spindle by the spindle itself. The lower end of the spindle is provided with an annular groove f, and, as herein represented, the supporting-case at 5o and within its lower end is provided with a screw-thread to receive a chambered nut g,

made cup-shaped and having its inner end beveled to act against the rolls c, kept in position between the said nut and the lower end of the sleeve a.

By the employment of the sleeve and the separate collar e and the separate nut g it is possible, by simply rotating the nut g, to so adj ust the parts as to compensate for any wear between the bearing-balls and the parts 6o upon which they run or rest as they move.

The spindle has attached to it a sleeve- Whirl B, having, as represented, a spherical top B', the bobbin B2 taking its upper bearing upon the upper end of the blade of the spindle and its lower bearing upon the spheri cal top of the whirl, the bobbin herein represented having an additional bushing near its lower end to contact with the blade of the spindle. v

The construction, Fig. 3, differs from that shown -in Fig. 1 only in that the sleeve marked m, which corresponds with the sleeve c, is made in one piece with the part m', whereas in Fig. l the corresponding part e is separate 75 from lthe sleeve. In Fig. 3, however, the rotation of the nut g in the supporting-case will enable any wear to be taken up at and about the lower set of rolls c.

In Fig. 2, on an enlarged scale, I have shown 8o the balls enlarged.

The lower set of balls c, by entering the groove fin the lower end of the spindle, bei sides serving as a lateral bearing, also act to sustain the weight of the spindle.

I claiml. In a spindle-bearing, a supporting case or shell combined with a sleeve therein, a series of balls or rolls supported at or near the upper end of the said sleeve, a series of balls 9o located at or near the lower end of the said sleeve to serve as upper and lower bearings for a spindle, combined with a nut to support the lowermost series of rolls or balls, substantially as described.

2. In a spindle-bearing, a supportingcase having' within it a sleeve combined with acollar, as e, and a nut, said collar and nut being located at or near opposite ends of the sleeve, a series of balls or roller-bearings located beroo tween the said sleeve and the said collar and nut and ser-ving as bearings for the spindle,

the combination being and operating snbstantially as described.

3. In a spindle-bearing, a supporting oase or shell internally threaded at one end and having an inturned flange at its other end, combined With a sleeve in said shell, a collar abutting against the flange, a nut in said threaded end of the shell, and a series of balls 01' roller-bearings located between said sleeve 1o andthe collar and nut to serve as bearings name to this specification in the presence of I5 two subscribing Witnesses.
